Receptive field map of DNOVS1. a Receptive field of DNOVS1. b Expected receptive field for DNOVS1, calculated by a summation of the receptive fields of VS6 and VS7 (Fig. 2), strongest coupled to DNOVS1 (Haag et al. 2007). c Difference between the receptive field of DNOVS1 and the expected receptive field. d DIs between the average receptive field (RF _mean) and each measured receptive field (RF _n) of DNOVS1 (gray dots) and the DI between the average receptive field (RF _mean) and the expected receptive field (RF _exp) marked with a black square. Data represent the mean responses recorded from n = 4 DNOVS1 cells
